Dollar Rally Faces End-of-Year Headwinds

According to dollar seasonality, September offers the strongest record for the U.S. dollar, with a 56% win rate and average returns of approximately 1.05%. However, even in this favorable month, losing months outperform winning ones, with an average negative return of 2.2% versus 1.9%. The seasonality pattern weakens as the year progresses, particularly in December, which carries the lowest win rate for the dollar and the most negative returns.

Market analyst Matt Simpson notes that 'this is quite an established well-known pattern' where the closer we get to the end of the year, the more likely it is for the dollar rally to fizzle out. With two Federal Reserve meetings scheduled before the seasonal low point in December, market pricing may overestimate the central bank's ability to hike interest rates.

The U.S. dollar has rallied on expectations of tightening, but actual guidance from the Fed remains unclear. Crude oil prices have also contributed to elevated inflation expectations and a hawkish stance. If crude were to pull back, it would remove key support for the tightening narrative, which is already facing headwinds from the calendar.
